> Sometimes BADA, DEB or CEB error interrupts occur when sd card is
> unplugged during data transfer. These interrupts are currently ignored
> by the interrupt handler. But, this results in card not being
> recognised on subsequent insertion. This is because mmcqd is waiting
> forever for the data transfer(for which error occurred) to complete.
> Fix this, by reporting BADA, DEB, CEB errors to mmc-core as -EILSEQ, so
> that the core can do appropriate handling.
